Performance and Benchmarks
System performance was great thanks to the 2.7GHz Intel Core i7 processor and 128GB Samsung SSD. Although our review unit only came equipped with standard Intel HD 3000 integrated gaphics, Dell also offers NVIDIA NVS 4200M discrete graphics with Optimus and 512MB of dedicated DDR3 memory. For those of you who aren’t familiar with NVIDIA Optimus technology, this is a graphics solution that automatically switches between Intel integrated graphics (for general computing and extended battery life) and the discrete graphics (for high-performance video editing, GPGPU computing or gaming).

In terms of standard day-to-day computing needs, the E6420 ATG worked flawlessly loading up web browsers or office productivity applications. Although our review unit didn’t come with discrete graphics the Intel HD 3000 graphics worked just fine for streaming HD movies over the web and was even powerful enough to handle a game or two … just in case you’re a bored road warrior. The 128GB Samsung PM810 SSD in our review unit was probably the single biggest contributor to snappy system performance; Windows startup was quick, applications loaded in a snap and application switching (multi-tasking) was faster than what you might get from a laptop using a standard 7200rpm hard drive.
